Misuse of antibiotics in people and livestock is rampant, and has caused the formation of antibiotic-resistant germs to speed up. As a result, scientists are trying to create new antibiotics that will fight the germs that existing antibiotics can’t fight.

Scientists are using varying methods to develop new antibiotics, such as adding silver, which can increase the antibiotics’ ability to combat germs. Researchers are also employing the bacteria’s own genetic sequencing to accelerate the creation of more powerful drugs.

In the US, almost two million people are infected yearly by antibiotic-resistant bacteria, resulting in thousands of deaths. It’s natural for antibiotics to become less efficient over time: bacteria develops a resistance, which means new antibiotics need to be created regularly. Both misuse of antibiotics and a decline in antibiotic development since 1990 have added fuel to the fire.

Researchers now have the capability to develop new antibiotics by studying germs’ genomes and looking for certain gene patterns. Most antibiotics are cultivated from the bacteria’s toxins—analyzing a germs’ genes has proven to be a great, albeit slow, method to creating new antibiotics.

Researchers are also looking for ways to render germs powerless. A person becomes infected when the bacteria’s population grows to a certain amount; scientists are trying to figure out if there’s a way to break communication between the individual microbes. In addition, scientists are trying to subdue toxins and other signaling molecules that are fundamental for an infection to advance.
